The mouthpiece I bought is the Thein RCMF, which is 32,7 mm and has an 8,0 mm bore. Rim width is 7,55 mm, very comfortable.
-- VERY nice looking mouthpiece, probably best silver plating I've seen. Some cool details on the shank/cup "joint", I'll post a photo tomorrow.
-- Sound: Whoa... I was truly surprised by the sound I get with this mouthpiece. It's like the tuba is familiar, but the sound is not. It's a lot clearer, more focused, but still very lively and full sound. Feels very efficient, and can get very loud, very easily. All around, really easy to play, and a lot of fun.
-- The above point could be very much based on the physical size/shape of the mouthpiece. This mouthpiece is smaller than what I've been using for the past 3 or 4 months, which admittedly is a very large mouthpiece. The Thein is more normally sized, and seems to be a better fit for my face.
-- Would another mouthpiece at another price have given me a similar result? I'm sure. But for some reason, I decided not to go that route.
Oh, and the people at Thein could not have been nicer!
So, there you have it. I'm the guy that needs to have funky shitt that nobody else has.
